Same Rain, Different Rivers: Catchments Vary in Turning Rainfall into Flow
A new study in Nature Water finds that the same amount of rain on the same landscape can send very different amounts of water into rivers at different times. The research provides a global picture of how consistently catchments turn rainfall into river flow.

The research offers a global picture of how catchments behave. It does not address where rivers are or how much water they carry. Instead, it focuses on how consistently landscapes turn rainfall into river flow. The key result: the same amount of rain falling on the same landscape at different times can send very different amounts of water into its rivers.
Our view
The study's focus on consistency, rather than location or volume, shifts attention to the variable relationship between rainfall and river flow.
What the reporting says: According to the source, a new study in Nature Water finds that the same rain on the same landscape can send different amounts of water into rivers at different times, offering a global picture of how consistently catchments turn rainfall into river flow.
